CHIMNEY-COWL- Specification of Letters Patent.

Patented March 5, 1907.

Application filed March 14,1906. Serial No. 306,066.

To all whom, it may concern:

Be it known that I, EDGAR S. EGY, a citi zen of the United States,residing at Storm Lake, in the county of Buena Vista and State of Iowa,have invented a new and use ful Chimney-U0wl, of which the following isa specification.

This invention relates to chimney-cowls,

and has for its object to improve the construction and increase theelliciency and utility of devices of this character.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the invention consists in certainnovel features of construction, as hereafter fully described andclaimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by like designating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation.

' In the drawings, Figure 1 is a vertical sectional view of a portion ofa smoke-stack and the improved device applied thereto. Fig. 2 is a sideelevation of the cowl or hood portion of the device with the bracketmember attached, the latter in its straight or unbent conditon. Fig. 3is a perspective view of the hood or cowl portion of the device. Fig. 4represents the base or support, and Fig. 5 represents the bracketmember, detached, in their unbent forms. Fig. 6 is a front view of theupper or socket end of the hood or cowl.

The improved device comprises a base or supporting member adapted to besupported upon any size of smoke-stack or chimney, a standard supportedvertically in said base member, a bracket swinging upon said standardand adjustable to adapt it to the size of stack or fine, and a cowlhaving means for attachment to the bracket.

The base member is in the form of a bar 10, having-a central aperture 11and extending over the stack represented at 12, and with the ends bentdown and riveted at 13 to the stack.

The bar is furnished in straight form, as in Fig. 4, with marks at thepoints where the same is to be bent to guide the workman in attaching tothe stack.

The standard 14 is formed with a head 15 at the upper end and threadedat the lower T end, where it passes through the aperture 11 inthe basemember, and secured position i by nuts 16 17, bearing upon oppositesides of the base member, and with a washer 18 bearing loosely upon theupper nut 16. The standard is thus readily adjustable verticallyrelative to the base member and stack, as will be obvious.

The bracketis furnished in the form of a bar 19 with apertures 20 21 atthe ends and with one end bent at an angle, as at 22, and adapted to bebent at an intermediate point to bring the end apertures in alinementand in position to rotatively engage the standard 14 between the head 15and the washer 18. The end portion 22 and the lower bent portion arethus disposed in a horizontal position, while the body of the'bracket isdis posed at an angle to the vertical plane of the stack and standard,as shown in Fig. 1. A washer 23 is disposed loosely upon the standard 14between the head 15 and the portion 22 or the bracket.

The bracket may be bent at any desired intermediate point to adapt ittothe size of the stack and is supplied with marks where it is to bebent to aid the workman in attaching to the standard. The bracket isthus the washers 18 23 materially reducing the friction.

l The cowl portion of the device is formed from a disk 24 of sheet metalpressed into shallow dish-like form and with a portion at one edgecrimped or compressed into a socket 25 to receive a vane 26, the lattersecured by rivets 27.

T he cowl thus constructed is riveted at 28 to the inclined portion ofthe bracket 19. hen thus constructed and applied, the wind blowing overthe stack operates upon the vane 26 and holds the body 24 of the cowl inthe path of the wind and shields the discharge end of the stack andefiectually prevents the wind from blowing down the same.

The device is furnished to the trade -knocked down, with t e base member10 in straight form, as in Fig. the standard 14 with its washers 18 and23 and nuts 16 17, the bracket with the short bond 22, and the cowl 24with its socket 25 and vane 26 in position therein. The partsthussupp'lied can then be readily a plied to any size of stack orchimney by liending the parts 10 and 19 at the points marked, rivetingthe member 10 to the stack, and riveting the cowl 24 to the bracketafter the latter is p0- free to swing around the standard as a center,

sitioned upon the standard, and the'standard connected to the basemember by the nuts 16 17.-

The device is simple in construction, can be inexpensively manufactured,and readily applied as before noted.

Having thus described the invention, What is claimed is 1. As a newarticle, a chimney-cowl formed from a sheet of metal pressed into dishshape and with a portion at one side crimped to form a socket havingspaced parallel sides, a vane having an extension bearing in saidsocket, and fastening means extending through the sides of said socketand also through the vane extension disposed between them.

2. In a device of the class described, a base formed from a bar adaptedto be bent at the ends for bearing over a smoke-stack, a 20 standardsupported upon said base, a bracket formed from a bar bent at an anglethereto near one end and bent at an angle thereto at a greater distancefrom the other end and bearing at said bent ends over said standard, 25a'eowl formed from a sheet of metal bent into dishing shape, means forattaching said cowl to the intermediate angular portion of said bracket,and a vane attached to said cowl. 0 In testimony that I claim theforegoing as my own I have hereto affixed my signature in the presenceof two witnesses.

EDGAR S. EGY.
